"This is a legendary divine artifact that can communicate with the Undead Empire. It possesses unparalleled power, able to disregard material entirely and strike at the soul directly..." Misha pulled out a necklace from her chest, excitedly introducing it, but was interrupted by Negris before she could finish.
"Isn't this the necklace of the lead singer banshee from the Howling Opera troupe — the Necklace of the Wailing Voice? How did it end up with you? No wonder you've been able to develop your iron skin within just two short years. It must be the Necklace of the Wailing Voice. This object can strengthen the soul, and if there is still soul energy inside, it can replenish your own. Where did you pick it up?"
Negris recognized this object, the Howling Opera Troupe, an opera troupe composed entirely of wailing banshees.
Wailing banshees are a very rare type of undead, evolved from wraiths. They possess a certain level of intelligence and are most proficient at using Soul Impact.
